One pound of grout is enough to grout a tiled area that is 110 sq. ft. Alyssa’s kitchen counter is made up of two rectangular segments. One is 10.3 ft by 2.5 ft, and the other is 3.1 ft by 2 ft. Which expression represents the number of pounds of grout Alyssa will need? (Hint: Area 1st Rectangle = (10.3)(2.5); Area 2nd Rectangle = (3.1)(2); Total Area = Area 1st + 2nd)

10.3(2.5) + (3.1(2) ÷ 110)
10.3(2.5) + 3.1(2) ÷ 110
(10.3 (2.5) + 3.1 (2)) ÷ 110
3.1(2) + (10.3)(2.5) ÷ 110

Which expression is equivalent to sq-80

Define multiplicative inverse. give an example of a number and its multiplicative inverse.

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.
